Abstract

Une station de base transmet une pluralité de symboles d'un canal de synchronisation primaire (PSC) à une station mobile dans un intervalle d'une sous-trame d'un système de communication sans fil basé sur des trames. La station de base transmet également une pluralité de symboles d'un canal de synchronisation secondaire (SSC) à la station mobile dans l'intervalle de la sous-trame. La station mobile détermine un faisceau récepteur préféré en se basant sur la pluralité de symboles PSC consécutifs reçus.
